CX have already said they'll oppose any move by QF to do this on Place of Principle Business laws.
They'll win, and this plan, like the others before it from this inept Qantas management will go the way of the dinosaur.
I don't think the 9th floor has got much to worry about from Qantas management who said 777's were "old technology", thought flying to less places would attract more customers, and who decided that grounding the airline was positive for the brand.
